JARED lVI. RICKARD, OF PASADENA, CALIFORNIA.

FOLDING SUPPORTv FOR STRAINERS, &o.

To all whom t may concern.'

Be it known ,that I, JARED M. RIOKARD, a citizen of the `United States,residing at Pasadena, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in FoldingSupports for Strainers, &c., of which the following is a specification.

This invention relates 4to a folding frame or support for strainers,etc., the primary object of the invention being to provide a support forholding coffee straining sacks or other articles while in use, whichsupport may be readily and conveniently folded in close compass forstorage or transportation.

A further object of the invention is to provide a folding frameorsupport of the character described which is simple of construction,reliable and eiicient in action,

and which embodies a minimum number of parts adapting the device to beeconomically manufactured.

The invention consists of the features of construction, combination andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the accompanying drawing, in which Figure l is aperspective View of the folding frame or support as set up for use.

Fig. 2 is a vertical transverse section through the same, showing themode of use of the device in supporting` a cloth strainer or the like.

Fig. 3 is a side view of the device in folded or collapsed condition.

Fig. 4 is a transverse section through the top of the device, showinganother use of the invention.

Referring now more particularly to the drawing, my improved foldingframe or support comprises a frame structure of substantiallyfrusto-conical form. This frame structure consists of a bottom ring 1formed of wire, and a pair of top rings 2 and 3, also formed of wire,and a pair of diametrically disposed standards or uprights 4 and 5respectively connecting the said top rings 2 and 3 with the bottom ring1.

As shown, the bottom ring 1 is provided at diametrically opposite sideswith upstruck U-shaped keepers 6 and 7 while the rings 2 and 3 arerespectively provided with similarly shaped down-bent keepers 8 and 9.The uprights or standards 4 and 5 are also formed of wire, and saidstandards have their end portions coiled to provide pivotedSpecification of Letters Patent.

sleeves or eyes 10 and terminal stop arms 11, the sleeves 10 of theupright 4 p ivotally engaging the keepers 6 and 8, while the sleeves oreyes of the upright 5 pivotally engage the keepers 7 and 9. l

The rings 2 and 3, being formed of spring wire, are capable of expandingand contracting, and the ring 3 is made of slightly smaller diameterthan the ring 2 or is adapted to be expanded so as to lie upon theinterior thereof, whereby the ring 3 is adapted to serve as a lockingmember to hold the frame elements in set up condition and also as aclamping member to support a strainer rsack 12 or the like, ashereinafter described. The ring 3 is formed at intervals rwith anannular series of retaining tongues 13 adapted to projectv .beneath thering 2,

Vwhen the support is set up, to further hold the two rings 2 and 3 inlocking engagement and to prevent their disconnection and any liabilityof casual collapse of the frame.

The support is adapted to be set up by :disposing its elements into theposition shown in Fig. 1, in whichv it will -be seen that theuprights 4and 5 extend upwardly from the bottom ring 1, which may rest upon Yafloor, table or other foundation, and that said uprights 4 and 5 supportthe rings 2 and 3 at an elevation above the ring 1, the rings 2 and 3being sprung into interlocking engagement, as described, and furtherheld connected by the tongues 13, thus keeping the uprights 4 and 5rigid and preventing said uprights or the rings from having relativepivotal motion on one another. When the parts are in the set up positionshown in Fig. 1 the stop members 11 abut against the coperating keepers8 and thus serve to limit the pivotal motion of the elements in onedirection and to rigidly brace and support the parts in set upcondition.

In Fig.v 2 I have shown one of the many and various uses to which myinvention may be put, the device being shown in this instance as asupport for a coffee straining sack 12, which depends from the upperrings 2 and 3 into the space bounded by the collapsible frame Vand ispassed at its upper edge over the ring 3 and clamped between the sameand the ring 2. To release this sack 12 for disconnection it is simplynecessary to spring the ring 2 out of engagement with the ring 3, aswill be readily understood. In Fig. 4 I have shown the device used as asupport for a body of screen wire or similar material 14, clampedl asdescribed between the frame rings, Which screen may serye as a grate,adapting the device to bey used over a camp fire or heater for cookingor analogous purposes. The device may be employed for clamping andsupporting various Varticles of the character described, thus renderingit capable lof being used for many and varied purposes. flierrit isdesired described my invention, I claim 2:-

1. A folding or collapsible frame support.

comprising ,a bottom ring, La pair of'top rings adapted for interlockingengagement with eacli'rotheigand folding uprights pivotally connectingAthe bottom ring.y with the respective top rings. v l

2. A folding frame support comprising a bottomlring, apaii of toprringsof resilient material .adaptedto be sprunginto interlocking engagementwith eachv other, and nprights fpivotally connecting ,the bottom ytofold ory collapse the device, this is effected byv springing the ringsring with the top rings to adaptsaid rings a bottom ring, apair ofresilient top ringsV adapted to be sprung into engagement with eachother, one of said rings being adapted to lie Within the other, and oneof said rings having tongues to engage beneath the other, and uprightspivotally connecting vthe botf toni ringivith the respective'top rings.

4f. 'A Vfolding frame support comprising,f.

a bottomring, a pair of top rings adapted for, interlocking engagement,said'rings havin L-U-shaped keepers offset therefrom, an,V uprightvpivotallyy engaging .offsets of the bottom ring and one of thetopi-ings and an upright pivotally engaging offsets of the bottoni ringand the other top rino:

5. A folding frame support*4 comprising a bottom ring havingdiametrically disposed U-shaped keepers, a pair of resilient `top ringseachhaving asimilar keeper,V` thekeepers of the top rings' beingdisposedto lie opposite each other, said top rings beingv adapted forinterlockingengagement, andi uprights having coiled Y.portions Y formingeyes pivotally engaging the uprights ofthe bottom ring iviththe uprightsofthe respectivetop rings, said eyes being vprovided with terminal stopsto abut against .the offsets Y and brace the frame elements whendisposed p in set. up'y condition.
